Description

Novel catheter

Technical Field

The utility model relates to the technical field of urethral catheterization apparatus, in particular to a novel urethral catheter.

Background

In clinical work, some special patients need to use the catheter, the catheter is a pipeline made of natural rubber, silicon rubber or polyvinyl chloride (PVC), and can be inserted into the bladder through the urethra so as to drain urine, after the catheter is inserted into the bladder, an air bag is arranged near the end of the catheter to fix the catheter to stay in the bladder and is not easy to drop out, and the drainage tube is connected with a urine bag to collect urine.

At present, after a catheter is kept in place, the length of a urine bag externally connected to a urethral orifice is generally 60cm-65cm, and the patient needs to be actively or passively turned over in bed for treatment and nursing, the body of the patient is repeatedly moved for many times, the catheter is kept in place and is very easy to be pulled off by external force, even the phenomenon of accidental tube detachment or tube drawing occurs, and the catheter repeatedly moves in the urethra to damage the urethral wall and the bladder wall, so that mechanical inflammation is caused, the pain of the patient is increased, and the treatment effect is reduced.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned condition, for overcoming prior art's defect, the utility model aims at providing a novel catheter, the effectual current catheter of having solved uses inconveniently, easily appears taking off the pipe and causes mechanical inflammation, reduces treatment's problem.

The technical scheme of its solution is, the utility model discloses a catheter, the catheter right-hand member is equipped with the drainage tube, the inside toper structure that is little and the right-hand member is big for the left end of drainage tube, the drainage tube right-hand member is fixed with a plurality of cowl plates along its circumferencial direction evenly distributed, every two adjacent cowl plates contactless, a plurality of recesses along the drainage tube circumferencial direction equipartition are all seted up on every cowl plate, but be equipped with the steel ball of rotation in the recess, a left end external diameter is less than the circular cone platform shape of its right-hand member external diameter for a plurality of cowl plates constitution, drainage tube circumference outside sliding connection has the sleeve pipe that is located its right side, sheathed tube internal diameter equals with the biggest external diameter that circular cone platform shape was constituteed to a plurality of cowl plates, the arc wall that is located the drainage tube right side is seted up to the sleeve.

Compared with the prior art, the beneficial effects of the utility model are that: set up catheter and collection urine bag detachable structure, avoided keeping somewhere the catheter too long, the patient stands up or when moving with the catheter tractive and deviate from, reduces the catheter and removes the damage probability to urethral wall and bladder wall repeatedly, avoids causing mechanical inflammation, reduces patient's misery, improves treatment, this simple structure, convenient operation conceives novelty, the practicality is strong.

Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

The catheter comprises a catheter 1 shown in figures 1 to 6, a drainage tube 2 is arranged at the right end of the catheter 1, a conical structure with a small left end and a large right end is arranged in the drainage tube 2, a plurality of arc baffles 3 which are uniformly distributed along the circumferential direction of the drainage tube 2 are fixed at the right end of the drainage tube 2, every two adjacent arc baffles 3 are not contacted, a plurality of grooves 4 which are uniformly distributed along the circumferential direction of the drainage tube 2 are arranged on each arc baffle 3, autorotative steel balls 5 are arranged in the grooves 4, the arc baffles 3 form a cone frustum shape with the outer diameter of the left end smaller than that of the right end, a sleeve 6 which is positioned at the right side of the drainage tube 2 is connected outside the circumference of the drainage tube 2 in a sliding manner, the inner diameter of the sleeve 6 is equal to the maximum outer diameter of the cone frustum shape formed by the arc baffles 3, an arc-shaped groove 7 which is positioned at the right, the right side of the drainage tube 2 can be connected with a urine collection bag.

The right end of the drainage tube 2 is connected with a plug 10 which can be inserted into the drainage tube 2 through a pull rope 9, the plug 10 is of a conical structure with a small left end and a large right end, and the plug 10 is provided with an annular groove 11 corresponding to the groove 4.

In order to achieve better urine collection effect, the urine collection bag is provided with a cannula which has the same shape and structure as the plug 10.

For better sealing, an annular sealing gasket may be provided between the drainage tube 2 and the plug 10.

In order to prevent urine in the urine collection bag from being squeezed and flowing back into the urinary catheter 1, a one-way valve 12 with an opening facing the drainage tube 2 is arranged in the urinary catheter 1.

The left end of the catheter 1 is provided with a plurality of urine inlet holes 13, and the catheter 1 is provided with a saccule 14 positioned on the right side of the urine inlet holes 13.

In order to enable the sleeve 6 to smoothly slide on the drainage tube 2, a plurality of T-shaped chutes in the left and right directions are formed in the outer edge surface of the drainage tube 2, the T-shaped chutes are uniformly distributed along the circumferential direction of the drainage tube 2, and a plurality of T-shaped blocks which can be in one-to-one correspondence with the T-shaped chutes are arranged on the inner side of the sleeve 6.

When the utility model is used, one end of the catheter 1 provided with the urine inlet hole 13 is inserted into the bladder through the urethra, the saccule 14 expands in the bladder, and the end of the catheter 1 provided with the urine inlet hole 13 is fixed in the bladder, so that the catheter 1 can be prevented from moving repeatedly in the urethra when a patient moves or turns over, and the urethral wall and the bladder wall are damaged;

the medical staff slides the sleeve 6 leftwards with the left hand, so that the sleeve 6 slides leftwards on the drainage tube 2 and compresses the spring 8, at the moment, the arc-shaped baffles 3 are separated from the constraint of the sleeve 6, the plug 10 is pulled rightwards with force by the right hand, and the steel ball 5 in the arc-shaped baffles 3 is separated from the annular groove 4 on the plug 10;

at the moment, the intubation tube on the urine collection bag is inserted into the drainage tube 2, so that the steel balls 5 on the arc-shaped baffles 3 enter the annular groove 4 on the intubation tube, then the left hand is released, the sleeve 6 pushes the sleeve 6 to slide rightwards on the drainage tube 2 under the elastic action of the spring 8, and as the arc-shaped baffles 3 form a cone frustum shape with the outer diameter of the left end smaller than that of the right end, the sleeve 6 extrudes the right ends of the arc-shaped baffles 3 inwards, so that the intubation tube is fixed in the drainage tube 2;

a valve on the urine collection bag is opened, the negative pressure in the urine collection bag opens a one-way valve 12 in the catheter 1, and urine enters the catheter 1 through a urine inlet hole 13 and flows into the urine collection bag; after the urine drainage is finished, the valve on the urine collection bag is closed, the intubation tube is taken out from the drainage tube 2 like the plug 10, at the moment, the one-way valve 12 is closed, and in order to prevent bacteria from entering the drainage tube 2, the plug 10 is arranged in the drainage tube 2.

In order to achieve better using effect, the middle drainage tube 2, the sleeve 6, the plug 10 and the intubation tube on the urine collection bag of the utility model can adopt plastic materials.
